CAN-FILLING- MACHINE.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed April 11,1908. Serial No. 426,510.

To all whom "it may concern:

Be it known that it, Grouse HENRY MAL- LETT, a citizen of the United States, and a resident of Copake, in the county of Columbia and State of New York, have invented a new and Improved Can-Filling Machine, of which the following is a full, clear, and exact description.

This invention relates to can filling machines of the general character shown in Letters .latent No. 870,979, granted to me November 12, 1907, for weighing machines. The means shown in said Letters Patent, however, are designed for filling cans with a powdered or granulated material, whereas the special purpose of this invention is to provide means for filling the cans with coffee and other commodities in a whole or unground condition, and to enable the material to be readily and evenly delivered from a hopper to the receiving cans.

Other objects relating to the special construction and special arrangement of the several parts will be understood from the following description and accompanying drawings, in which drawings like characters of reference inr'licate like parts throughout the views, and in which- Figure 1 a side elevation of a device embodying my invention provided with a hopper, partly broken away; rig. 2 is a horizontal section taken on the line 22 of Fig. 1; and Fig. 8 is a horizontal section taken on the line 33 of Fig. 1.

As illustrated in the drawings, the main frame of the device consists of vertical standards 1, provided with cross arms 2 having a bearing 3 for a rotating shaft 4, the upper end of the shaft being provided with a beveled gear 5 which meshes with a correspondingly beveled gear 6 fixedly attached to a shaft 7 which shaft is journaled in bearings 8 and provided on its outer end with a drive wheel 9 having a clutch 10 of ordinary construction attached thereto. A scale for weighing the material may, if desired, be used in connection with this invention and an auxiliary frame supported upon the platform 11 of the scale. This auxiliary frame consists of vertical standards 12 having a transverse shelf 13 attached thereto, and adapted to receive a tray 14 which holds a plurality of receiving cans 15, the open ends of which cans are arranged in line with the lower ends of a plurality of pockets 16 having their lower ends provided with trap doors 17 and hinge pins 18, by means of which the doors are secured to the pockets. Sprin 19 are connected with the trap doors and the pockets so as to close said doors against the bottom of the pockets. A re ciprocating rod 20 is mounted to slide longitudinally in the uprights 12 of the auxiliary frame, and provided with laterally extending arms 21 which are connected with the free ends of the doors 17 of the pockets, thereby adapted to open and close said doors in unison. The upper ends of the pockets are arranged in line with chutes 22 attached at their upper ends to the base 23 of a hopper 24. The base of the hopper is attached to the uprights 1 of the main frame, and is provided with a plurality of discharge apertures 25 which are preferably arranged in a circular line, as shown in Fig. 3, while the pockets 16 may be arranged in straight lines, if desired, the outer pockets being in clined at their lower ends so that the lower ends of said pockets will extend in line with each other. Blades 26 are attached in any suitable manner to the outer portion of a disk 27, which disk is rigidly attached to the shaft 4. The diameter of the disk 27 is less than that of the hopper 4, leaving a space between the outer periphery of said disk and the inner wall of the hopper for the material within the hopper to drop down on to the base of the hopper between the blades 26, While the disk 27 serves to support the bulk of the material in the hopper and prevent said material from packing together. After the material within the hopper has dropped between the disk 27 and the inner wall of the hopper 24, said material is drawn inward by the curved blades 26 and drawn over the apertures in the base of the hopper which are below the plate 27, thereby enabling said material to pass through the openings 25 in the base of the hopper, the chutes 22, and into the pockets 16 from whence the material is discharged into the receiving cans 15. The blades 26 preferably correspond in number with that of the discharge apertures in the base of the hopper, and these blades are preferably spaced from each other to correspond with the distance between the apertures in the base of the hopper so that each blade will feed an equal amount of material into the pockets 16 arranged below the chutes 22 connected with the openings in the hopper.

The disk 27 by extending over the aperes of the hopper not only supports the terial Within the hopper, but also prents the material in the hopper from choksaid discharge apertures and enable a p rtion of the material in the hopper to fall between the disk 27 and the Wall of the hopper, and be drawn under the disk 27 by the blades :16 thereby insuring an even distribution of material into the respective chutes and pockets connected therewith.

Having thus described the invei'ition what I claim as new and desire to secure by Letters Patent is:

l. The combination With a hopper provided with a plurality of discharge apertures, of a rotatable shaft arranged Within said hopper, a, disk fixedly secured to said shaft and arranged Within said hopper with its periphery spaced from the inner Wall of said hopper, and extending over said dis charge apertures, and a plurality of blades having their inner ends arranged back of said disk and adapted to tavel over said apertures, and their outer ends extending approximately to the inner wall of said hopper.

2. The combination with a hopper provided with a plurality of discharge apertures of a rotatable shaft arranged within said hopper, a disk fixedly secured to said shaft, smaller in diameter than that of the hopper, extending over said discharge apertures, and a plurality of curved blades arranged back of said disk and adapted to sweep over said discharge apertures and to extend at their outer ends approximately to the inner Wall of said hopper.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

GEORGE HENRY MALLETT.
